200x high and hanging idle ???

That could be coil issues. Get an ohm meter and read the coil, cdi pick up and the plug that comes from the flywheel, they should match what the book shows for ohms when cold and should be the same when the machine is hot. If they are not the same when it's warm you found your problem. Change whatever part is broken/malfunctioning.

Got a multimeter, I'll check that out...excuse the noob electrical question - I can check electrical resistance (ohm) without the bike running right??

It sounds like you may be tuning the carb when the motor is still cold, and then when the motor warms up it completely throws everything off

hmmm...i though about that last night...I made the final adjustments after about 20 minutes of revving, idleing etc...was pretty warm I think?

[rdlsz24]

Yeah that should be fine

Yep checking the ohms you will want to do when the machine is off. Just unplug the wires and check the readings, they should be within spec of what the service manual says.

idel is the low end along withthe pilot jet, once you get into it hard, it will need a possible bigger jet or smaller jet for running correct at WOT.

True but if he gets it running correctly until everything gets warmed up that could lead to believe it's electrical. If jetting is stock on a stock motor there shouldn't be a lot of carb tuning to do to get it to run somewhat decent. Even if the main jet was off a few the idle should be able to set between the air mixture and the idle screw.


IDk just thinking out loud.

Ran it last night quite a bit...it wouldn't die on me like before but it was cold last night (upper 30's).

Tried different plugs, they all came out lean...ran the bike at all different RPM and loads...runs great...but lean. I even took the opportunity to clean up some old fouled plugs

Didn;t bother to test ignition because it ran all night. The warmer the bike got, the more i had a tough time getting it to idle on it's own. Still ran great though - no hesitation, smooth clean power.

Oh yeah - I checked the mixture screw, it was at 1.5 turns from yesterday so I left it. Tried moving it to 2 turns at one point...didn't really help. The idle screw ends up approx 4 turns out.

Gotta be an air leak somewhere. I RTV'd the intake boot to the carb a while back because the o ring was shot. I feel like an idiot, but I forgot about this. I got a new oring in the carb kit - think this is worth a shot? clean the RTV out and install the o ring????

[oscarmayer]

yea he can get it close wikid500.
sounds like the main jet is too little or
did you try loosening your gas cap? maybe the vent is jacked and restricting flow.
also is tehre a filter on the fuel line? can it be clogged? what about the peacock? is it ok? is the tank full of rust or rusty flakes floating round?

jsut thinking of stuff that can clog stuff and restrict flow.

thanks for the tips oscarmeyer...

Main jet is 108, stock for this bike from what I have been told...I've cleaned the carb 3 times, drained and cleaned the tank, filter sock in the tank and petcock once (i check the petcock for flow each time I test it just to make sure)...

I have tried running with the cap loose and no difference (blew through the line too)

I don't have an inline filter...where could I get one of those in a local store? Home Depot, Autozone maybe??
